The invention generally relates to pistols More particularly theinvention relates to that type of pistol which is in the form of afountain pen and operates to discharge an incapacitating fluid, such astear gas.

One object of the invention is to provide a pistol of this type which isgenerally of new and improved construction, may be manufactured at acomparatively low cost and is exceedingly etcient in operation,

Another object of the invention is to pro- -vide a gas dischargingpistol in which provision is made for preventing the pistol from beingused for ring cartridges containing bullets or projectiles.

Other objects of the invention will be apparent from a consideration ofthe following detailed description.

The invention consists in the several novel features hereinafter setforth and more particularly defined by the claims at the conclusionhereof.'

In the drawing: Fig. 1 is a side elevation of a pistol embodying theinvention; Fig. 2 is a. longitudinal sectlon. Fig. 3 is a section takenonl line 3--3 of Fig. 2. Fig. 4 is a section taken on line 4--4 of Fig2. Fig. 5 is a perspective of the clip for holding the pistol in apocket.

The invention is exemplified in a pistol comprising a cylindrical stock7 in which is slidably mounted aplunger 8. The outer end of this stockis provided with an internal screw-thread 9 to which a breech block 10is screw-threaded said block is preferably retained in a positioninwardly of the outer end of the stock, and has recesses 11 thereinl t0receive a key whereby it may be turned into and out of its operativeposition in the stock. In addition to the recesses, the block has acentral opening 12 through which a` firing pin 13 on plunger 8 isadapted to pass. A barrel 14 has its inner end exteriorly threaded tolit the screw-thread 9 on the stock 7, and is adapted to receive acartridge 15 containing material Which, when fired, will produce anddischarge an incapacitating gas, such as tear gas. The inner end ofthebarrel engages the rim of the cartridge, and is 5 adapted to be screwedinto position to holdunscrew the cap 18 from the stock 7.

securely Vthe cartridge against the breechI plug. To load the pistol,the barrel 14 is first removed from the stock and the cartridge isinserted into the barrel. Thel barrel, with the cartridge therein, isthen screwed into the stock until the rim of the cartridge is conlinedbetween the barrel and the breech plug. The plunger 8 is elongated so itwill slide freely in the stock 7, and is operated to lire the cartridgeby a coil spring 16, one end of which is held in a socket 17 in saidplunger and the other end of which is held in a socket 18 in a cap 19.The cap has a substantially cylindrical portion or stem 20 which extendsinto the stock 7 and is provided With an external thread 21 to'fit aninternal thread on the inner end of stock 7 to secure removably the capin place. The outer peripheries of the cap and stock are flush. A clipfor holding the pistol in a vest pocket comprises a ring 22 which isclamped between a shoulder 23 on the cap 18 and the inner end of stock7, and a resilient arm 24 which is provided at its outer end with a ball25 to grip a portion of the pocket. To remove the spring 16 or the clip,it is only necessary to By clamping the ring of the clip in this manner,it- Inay be rotatively shifted to bring the arm 24 into any desiredposition. A stud 26 is screw-threaded to the firing plunger 8 andextends through a longitudinally extending straight slotf 27 in thestock. This slot permits the plunger and tiring pin to be retractedagainst the forcey of spring 16. The stud has a hea-d 28 so it can bereadily engaged by a linger in retracting the plunger. To fire thecartridge, the user Will pull the head 28 ot' the stud'backwardly toretract the plunger vagainst the force of spring 16, and then releasethe plunger. Upon release of the plunger the spring Will impel theplunger outwardly with sufficient force to cause the firing pin 13 tolire the cartridge.

In a pistol for discharging cartridges for producing incapacitating gas,it is desirable to provide means to prevent the pistol from beingloader:l with a cartridge having a bullet therein. For this purpose, ablade 30 of thin metal is confined in and extends diafor cutting the wadof but a small number of parts.

metrically across the barrel adjacent to the outer end of the shell ofthe cartridge. The material .for producing gas is confined inv the shellof the cartridge4 by a wad 431, and the blade-30 is thin or has a.,sharp edge to 4sever the wad as it is projected from the shell of thecartridge, so it will be discharged from the barrel when thecartridge isfired. The blade `30 is provided with reversely extending varcuateportions 33 which fit in an annular groove 35 in the barrel. The bladeand arcuate portions are formed of resllient metal so said portions canbe sprung into the groove in placing the bladel into. the barrel. Thisexemplifies means for preventlng the insertion of a cartridgev with, abullet, and the tear gas cartridge when it is fired.

The bore of the barrel is flared outwardly,

as at 36, so as to cause the vgas to spread in aA flared column. Inpractice, it has been found that by spreading the column of gas, it ismore effective in reaching its intended mark thanvwhen it is projectedfrom a truly cylindrical barrel.

The gas discharging pistol herein disclosed may be manufactured at acomparatively low cost by virtue of the fact that it consists of Invview4 of the fact that the blade 30 is located so as to prevent the useof cartridges having bullets or I projectiles, the pistol may be usedWithout danger of inflicting permanent injury.

The invention is not to be understood as restricted to the details setforth, since these may be modified withinvthe scope of the appendedclaims, without departing from the spirit and scope of the invention.

lI-Iaving thus described the invention, what I claim as new and desireto secure by Letters Patent, is

1. In a fountain pen shaped pistol of the character described, thecombination of an elongated tubularv stock embodying an internal screwthreadA at one end thereof, a cap adapted to close the said one end ofthe stock and 'provided with a substantially cylindrical part extendingintothe stock, said part having formed therein an open-ended socket andembodying an external screw thread vfor engaging the aforementionedinternal thread and connecting the cap removably in place,

one end ofthe stock, and a wad-cutting blade extending across the boreof the barrel and disposed so that it is in close proximity to the outerend of the cartridge shell and op# crates to prevent the insertion intothe barrel of a cartridge with a bullet.

In a pistol, the combination of a cylin. drical stock, a spring-pressedfiring element in the stock, a breech plug in the stock, a barrel for acartridge, and I'a Wad cutter in the barrel -disposed adjacent the'outer end of the 4. In a istol, the combination of a cylin- :dricalstoc t, la spring-pressed firing element in the stock, a breech plug inthe stock, a barrel for a cartridge, provided with a groove,

and a blade having a resilient strip heldinl said groove. Y

5. In a pistol, the combination of a cylindrical stock, a springzpressedfiring element in the stock, a breech plug in the stock, a barrel Yfor acartridge, provided with a groove,and a blade having a member extendingacross. the'barrel and resilient members confined in said groove.

'cartridge shell to preventv insertion of a cartridge with a bullet'.
